想做一个公寓内人员信息管理、查询的系统或者程序。

想做一个公寓管理的简单系统，建立不同楼栋，楼层，房间的模型，实现对房间内人员添加，删除。根据信息检索查询。可以根据表格，批量导入房间的功能。
本人没任何基础，希望高人指点迷津，如需自学需要从什么开始。

不限语言？django做容易点

from django.shortcuts import render, redirect
from django.http import HttpResponse

from .forms import TenantForm, RoomForm

    return render(request, 'building.html', {'buildings': buildings})

    floors = Floor.objects.filter(building_id=building_id)
    return render(request, 'floor.html', {'floors': floors})

    rooms = Room.objects.filter(floor_id=floor_id)
    return render(request, 'room.html', {'rooms': rooms})

    tenants = Tenant.objects.filter(room_id=room_id)
    if request.method == 'POST':
        form = TenantForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('room', floor_id=form.cleaned_data['room'].floor.id)

      room_id = Tenant.objects.get(id=tenant_id).room.id
      Tenant.objects.filter(id=tenant_id).delete()
      return redirect('add_tenant', room_id=room_id)

            return HttpResponse('File is not CSV type')
        csv_data = csv.reader(csv_file.read().decode('utf-8').splitlines())
        for row in csv_data:

            room.number = row[0]
